Newhall Pass, Mountain pass in Los Angeles County, California.
Newhall Pass is a mountain pass in Los Angeles County that forms a natural gap between the Santa Susana Mountains and San Gabriel Mountains. This passage accommodates multiple transportation routes including Interstate 5, California State Route 14, Metrolink rail services, and the Union Pacific Railroad.
Spanish explorer Gaspar de Portolà discovered this mountain passage in 1769 and established a route between the San Fernando Valley and Santa Clarita Valley. Before receiving its current name, the location was known by different names including Fremont Pass and San Fernando Pass.
The pass is named after businessman Henry Newhall and serves as a vital link connecting the San Fernando Valley to the Santa Clarita Valley. Today it functions as a busy modern transportation corridor where residents and travelers move between different regions of Los Angeles County.
Visit during off-peak hours to avoid heavy traffic and enjoy clearer views of the mountain landscape. Keep in mind that this is primarily a functioning transportation hub, so pedestrian access is limited throughout the area.
Two major Los Angeles aqueducts traverse the eastern section of the pass, transporting water from the Owens River to supply the metropolitan region. These underground systems are invisible to visitors but essential to the city's water supply operations.
